That's probably because racers are a bunch of idiots, but motor bicycle riders as a group are highly intelligent genius mechanical engineers.

You seemed very interested in Opti-2 oil even though you have
never tried it.
I sent 2 packets of Opti-2 oil to your address that you PMed me
so that you could try it out and report back to the forum with
your test results.

However a few days ago I see you posted in the chat box that
you used the 2 packets of Opti- 2 to start some camp fires.

My only question is why did you do that?
 
Lets get back on subject and stop the petty squabbles and arguments. This has been a good discussion for a long time. Don't kill it with adolescent behavior.
 
Another guinnea pig

I'm in. I just finished a rebuild last night. Motor is a skyhawk gt-5 that I had to replace the top end due to prior damage. I decided to give Opti a shot after reading this epic thread so last night i mixed up a 1.8oz pack to a gallon of gas and fired it up for the first time.

First start was quick and it ran pretty well but I still have some tuning and break in to go through on the new cylinder, piston and head. It seems to be running a little rich so I may play with smaller jets as the clip is at the top.

I gotta say this stuff will win me over quickly so long as the motor doesn't totally fry. The lack of smoke and oily splatter from the exhaust is priceless.

I use a #73 wire gauge bit to redrill my jets after I solder them up and place my clip on the second from the top notch, works great on mine with the Opti2 @ 1.8oz per gallon

Yep the things you just said here are a couple of the best things about running the Opti2, my engine make good power on it as well and I have close to 1300 miles on one of them and still running strong


Peace, Shan

M/B are you using the nt or cns? 48 or 66cc? i'm running the cns2 on my 48cc, just drilled the main to a 66. It gave me more top end but still flatens out so i'm going to try a 65 friday. Running the SBP air filter lets alot more air in.
 
I have the NT carbs on all my engines right now, they are all tuned real nice, they will all hit 38-41MPH jetted like I described.

I have a DAX rt carb. thats going on one of them as soon as I have the time to do it. Had a lot going on here lately and not much time for my MB stuff.

Peace

Doesn't take long, the only stinky thing is getting the auto choke right, my only advice is assemble the carb with the filter OFF so you can see what you're doing, saves time and confusion lol :)

I've looked at the RT carb. and I can make that choke a manual choke pretty easy, I cant remember exactly what my plan was but I remember that I saw how it could be done without to much trouble even if I had to build a new block off plate to relace the one that comes in it.

There's a thread on this carb but I'll share this here.
Just remove the return spring and file off the little 'leg' that engages the choke plate. Install a compression spring where the original spring used to be to add friction and now you'll have a manual choke. I did this to one but the others I left the 'auto' choke operative. I don't see a lot of difference.
Now back to the 100:1 subject.

I have been running opti now for a while in my new build. I started it first time with break in with the opti runs great. I just put on a sbp expansion pipe and had to go back to the original jet cause it looked to be running lean now. I will now more tomarrow after tuning the pipe and test runs with plug chops.

The two plug chops I did first one with a 68 jet looked to lean then put the original jet back in and it almost looked the same but a tad darker to me. If that is to lean I just got a sodler gun and a mini dril bit set with handdrill from hf and i will use that starting on the #70 first.
 
Since opti had been working well in my bike, I just put the same opti-2 mix into my gas hedge trimmer. Seems to run smoother than before, but time will tell. I'd love to end up with only one gas can in my garage for the various 2 smokers. My only hesitation is my chainsaw; I will have to screw up my courage for that one.

Frankly, I was of the snake oil opinion, but it really does seem to be working well so far. I'll be totally sold after several more months of running.
 
Opti 2 will work fine in your chain saw, I have a 1983 poulan 3700 that runs better on opti than any other oil. I have never had the head off of this saw and cut fire wood every year with it. I run it at 70 to 1.
 
i have been using opti-2 for about 3 tanks @ 72:1.

my spark plug looks a little gooky to i think i will move to 100:1

i use to peddle half a block to get it started.
now i can start it between 1-4 car lengths. depending how warm it is outside.
